A woman in her 30s presented with a 15-year history of generalized asymptomatic papules on her body. The lesions had initially started from her left arm and gradually progressed to her trunk, legs, neck, and face in a symmetrical pattern within 1 year. She was otherwise healthy and had no family history of similar symptoms. Physical examination revealed widespread, monomorphic, skin-colored to red-brown papules 2 to 4 mm in diameter, and symmetrically distributed over her trunk, extremities, neck, forehead, and periocular regions (Figure, A and B). Punch biopsy specimens were obtained from the abdomen (Figure, C).
